Obeying the speed limit, accelerating and braking gently and gradually, and reading the road ahead can improve the fuel economy of your vehicle by 15%–30% at highway speeds and 10%–40% in stop-and-go traffic. Driving more sensibly is also much safer for you and others.
Smooth and gentle – drive smoothly, accelerate gently and read the road ahead to avoid braking unnecessarily. Decelerate smoothly by releasing the accelerator in time, leaving the car in gear. Keep rolling – stopping then starting again uses more fuel than rolling.
How can you save fuel while driving on hills? Reduce your speed as you move uphill and use your car's momentum to coast down the hill. Use Air Conditioning Sparingly: Your fuel usage can go up 20% when you are using your air conditioning. Try to recirculate the air instead of keeping it on full-blast.
1) Avoid Long Idling. 2) Clean Out the Trunk and Eliminate 3) Unnecessary Weight. 4) Keep Tires Inflated to the Correct Pressure. 5) Don't Buy Premium Fuel.
Drive smoothly and at the best average speed for MPG
As such, if you can make your speed changes more gentle, you'll create a slightly higher average speed, and see fuel economy improvements.
Switch off the engine at traffic lights or at a place where you have to wait. Ensure correct tyre pressure. Ensure regular maintainance of the vehicle. Drive at a constant and moderate speed.
In line with the above point, keeping the car moving at the right speed is essential to fuel economy. Obviously, this depends on traffic conditions and what's happening on the road ahead, but slowing down and having to accelerate again naturally uses more fuel.
The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly.
Many modern cars have an eco mode setting to improve the vehicle's fuel economy. While it's on, the engine reduces its power output, so it doesn't work as hard, and the gas pedals become less responsive. The reduction in power leads the car to accelerate more slowly.
The more fuel or energy-efficient the route, the lower your car's fuel/energy usage and CO2 emissions. If this feature is turned on, Maps uses fuel or energy-efficiency on top of other factors like real-time traffic and road conditions to choose the best route for you.
Fuel management is the act of managing and monitoring the fuel consumption of vehicles, typically within a fleet. This is necessary to ensure the effective management of a fleet and allows fleet managers to track the amount of fuel used by drivers within their fleet.
Air conditioning uses fuel
An air-conditioning (a/c) system can increase fuel consumption by up to 20% because of the extra load on the engine. The actual load depends on the vehicle's interior size, the outdoor temperature and other conditions.
Cruise control can help you become more fuel-efficient and can help you save an average of 7-14% on gas thanks to its ability to maintain a continuous speed. In comparison, the constant change in acceleration and deceleration of the driver placing their foot over the pedals can eat more gas.
Speeding increases fuel consumption and decreases fuel economy as a result of tire rolling resistance and air resistance. While vehicles reach optimal fuel economy at different speeds, gas mileage usually decreases rapidly at speeds above 50 miles per hour (mph).
A bad fuel injector or dirty/old fuel filter can drastically affect the flow of fuel into the engine. A fuel system problem is one of the most common causes of poor gas mileage. The more you run your A/C, the lower gas mileage you will get.
Estimates vary and other factors affect your miles per gallon but underinflated tyres could be increasing your fuel consumption from anywhere between 3% and 10%. Whatever the true figure, that will be having a direct impact on your wallet every time you fill up.
Pros of buying a diesel car
Due to diesel engines' increased fuel economy, you can get up to double the kilometres out of a tank, meaning less trips to the service station. Diesel fuel is less prone to price fluctuations than petrol. Some diesels are even more economical than hybrids and are cheaper to buy.
Velomobiles (enclosed recumbent bicycles) have the highest energy efficiency of any known mode of personal transport because of their small frontal area and aerodynamic shape.
What qualifies as fuel efficient, then? Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km.
